With sunlight the photovoltaic produces direct electricity. The generated direct electricity is converted to alternating electricity by the inverter. Through conversion, the alternating electricity can be fed directly into the public or privately used power grid, thus either reducing your own electricity costs. How much electricity does it produce on a normal day?
It is an important topic and a good way to save energy and to do something good for our environment. A good idea would be to install a photovoltaic system on every new building and so the electricity would be produced by itself.
Our idea would be to find out more about photovoltaics by interview people who has photovoltaics on their building.
